Unanswered question

As we all know, we always run performance tests against huge volume databases where we will have millions of records, As a consequence the neoload’s sql variables (I have plenty of them in my neoload project) try to fetch millions of records at the time of starting a test every time. Most of the times these variables return same set of data, so there should be some mechanism for the user to choose either fetch data or not to fetch data. In this way whenever it is relevant I can enable the fetching of data otherwise I would continue with already fetched data. This is really causing so much delays. Because of this the test starting time also very high.
